I can't install Eric4 too:
C:\Temp\eric4-4.4.19>d:python install.py
Checking dependencies
Sorry, you must have Python 2.6.0 or higher.
But the download page says that Python 2.5.0 or better is required.

Your download page doesn't show which file one should download. How could one
know that eric4-i18n-en-4.4.12.zip is a translation archive. Your download page
should be clear that one should look for eric4-X.X.X.zip archive and not for
eric4-iXXn-XX-X.X.XX.zip. When i extracted eric4-i18n-en-4.4.12.zip i saw
install-i18n.py only. Many hours later, i saw that i have downloaded the wrong
package. Thanks.
